Notes:
We measured the O 1s and Ti 2p X-Ray Absorption Spectroscopy (XAS) spectra of a series of ternary Ti oxides. The spectra of A12TiO5 are compared to those of TiO2 and the physical mixture TiO2-Al2O3. The spectra reflect important differences in the electronic structure caused by changes in the chemical bonding. It is also shown that XAS can be used to distinguish a true compound like Al2TiO5 from a stoichiometric mixture like TiO2-Al2O3. The differences in the spectra of NiTiO3, SrTiO3, BaTiO3 and PbTiO3 are discussed in terms of the different chemical environment and the local coordination. © 1997 by John Wiley & Sons, Ltd.
